PTCL DSL = No HDMI output.Wait I don't get it you said that only standard channels come on DSL right so after 2 months the cable operators are making you buy a digital box & hook up the cable with it & they say its HD , its basically in the name ''Digital'' box & the cable operators don't give fiber to home they give a copper line with a fiber back bone so how are they giving HD ???? & the only cable that can do digital is HDMI on tvs/consoles/DVD players & tv boxes ( I am aware that dvi & DP ( display port) are digital too but they're only on pc) So PTCL they're only providing the hdmi one on actual fiber? So I am guessing Nayatel must be giving one with HDMI since all their cables are fiber optic
& A/V is Analog right same as VGA input right? although vga can do 1080p but the quality is not the same as of a digital cable & A/V can do sound unlike VGA , A/V = Audio video
PTCL Fiber = HDMI output.
Nayatel Analog cable = Direct Coaxial from ONT to your TV
Nayatel HD Box = Ethernet from ONT to STB and HDMI from STB to TV.
